Drew Farris commented on MAHOUT-408:
------------------------------------
Thanks for the patch Shannon.
The patch applies cleanly, build completes and all unit tests pass. -h and
--help options now work for all mentioned operations.
The approach to handing transpose seems suitable.
This looks good to commit. Any other comments?

> Key: MAHOUT-408
> URL: https://issues.apache.org/jira/browse/MAHOUT-408
> Project: Mahout
> Issue Type: Bug
> Affects Versions: 0.4
> Reporter: Shannon Quinn
> Priority: Minor
> Fix For: 0.4
>
> Attachments: MAHOUT-408.patch
>
>
> The following Mahout programs incorrectly processed -h flags, throwing
> OptionExceptions:
> seq2sparse
> seqdirectory
> seqwiki
> svd
> trainclassifier
> transpose
> The first five are easily addressed by adding "parser.setHelpOption(helpOpt)"
> in the correct driver files (thanks to Jeff Eastman). The "transpose" program
> also contained a NullPointerException thrown when two integer arguments were
> not verified. See the patch file for a possible fix.
